The only direct drive I would have any interest in would be the STST Motus II. It is the only DD turntable I know of that is properly suspended. Otherwise stick to belt drive. It is a much safer bet.
The Thorens TD 1600 is an amazing turntable for the price. It has a great tonearm to boot. For $4000 you get a turntable that you can not surpass until you spend over twice as much.
